摘要： Embodiments of an apparatus for harvesting electrical power from fluid motion are described. The apparatus includes a magnetostrictive component having an internal pre-stressed magnetostrictive core. A magnetic property of the magnetostrictive core is configured to change with changes in stress within the magnetostrictive core along at least one direction within the magnetostrictive component. Also, forces at least partially due to fluid motion results in changes of stress within the magnetostrictive core and consequently change the magnetic property. The magnetostrictive component is further configured such that the change in the magnetic property will result in a change in the magnetic flux, which can be used to generate electrical power.

摘要： An apparatus harvests electrical power from mechanical energy. The apparatus includes first and second load-bearing structures, a plurality of magnetostrictive elements, and an electrical circuit or coil. The load-bearing structures experience a force from an external source. The magnetostrictive elements are arranged between the load-bearing structures. The load-bearing structures transfer at least a portion of the force to at least one of the magnetostrictive elements. In this way, at least one of the magnetostrictive elements experiences the force transferred from the load-bearing structures. The force on the magnetostrictive element causes a change in magnetic flux of the magnetostrictive element. The electrical circuit or coil is disposed within a vicinity of the magnetostrictive element which experiences the force. The electrical circuit or coil generates electric power in response to the change in the magnetic flux of the magnetostrictive element.

摘要： A method and device for using radial relative displacement between a magnet and coil to generate electricity from fluid motion. The device includes a support structural component, a movable magnetic structure, a rotating structural component, and bearings. The movable magnetic structure is coupled to the support structural component. The rotating structural component rotates relative to the support structural component. The bearings are coupled to or disposed with the rotating structural component. The rotation of the rotating structural component results in forces applied by the bearings on the movable magnetic structure and movement of the movable magnetic structure.

摘要： A system converts mechanical wave energy into electrical energy. The system includes a wave energy converter (WEC), which includes a surface float, a reaction structure, a plurality of flexible tethers, and a plurality of drivetrains. Each flexible tether connects the surface float to the reaction structure. Each drivetrain is connected to a corresponding flexible tether. Each flexible tether has a length established to treat the system as an inverse pendulum to utilize a horizontal surge motion of the surface float to present tension at the corresponding drivetrain for production of electrical energy from the horizontal surge motion.

摘要： An apparatus converts mechanical energy to electrical energy. The apparatus includes a linear electrical generator. The linear electrical generator includes at least one translator with translator poles and at least one stator with stator poles. The stator poles are aligned with the translator poles according to a Vernier scale. For given lengths of the stator and translator, the number of stator poles in the stator is offset by an integer number of translator poles in the translator.
